Any adequately equipped factory can produce high-quality, medium-quality, or low-quality guitars and basses. It all comes down to the materials used, the experience level of the builders, and the quality standard in place..[/QUOTE]
I have owned three MIM Strats (as well as three or four American). Overall build quality was right there. The gap for me was quality of electronics and hardware. My main strat started as a MIM strat 20 years ago but now has an AllParts neck and EMG pickups. Looks, plays, and sounds great, and it may be the one guitar I will have till I die. The others are all gone. What I didn't say is that I probably played 15 MIM Strats before I bought the one. They all felt played, and sounded different. This one had a body and neck that really resonated, and while I changed the neck to a chunkier profile I made sure I kept the resonance (and frankly got lucky).
I recently picked up a Squier Matt Freeman P (made in China) and while I some day may change the pickup that bass is just outstanding. Quality, fit, and finish are excellent. Of course, it is black and basswood, so I am sure corners were cut in the quality of the wood, but the outcome is great.
So, I am a firm believer in the quote above, and always play instruments unplugged before I buy to make sure they talk to me. If they do that they will SING through your rig.
